Google has opened up its gallery for developers to share Chrome extensions, a step that soon should make it easier for people to customize the open-source browser. Aaron Boodman, a leader of the Chrome extensions effort, announced the move on a mailing list posting Monday, and programmer and "gallery master" Lei Zheng shared details in a blog post. So far, only uploads are permitted. Google plans to let some testers use the gallery to download extensions, too "in the next few days," Zheng said. "We are making the upload flow available early to make sure that developers have the time to publish their extensions ahead of our full launch."
